M1030-2 MOTE DATASHEET DUST NETWORKS™

CONFIDENTIAL

Product Description

The SmartMesh-XT™ M1030-2 embedded wireless mote uses Time Synchronized Mesh Protocol (TSMP) to enable low-

power wireless sensors and actuators with highly reliable wireless mesh networking. The

M1030-2 is tailored for use in

battery- and line-powered wireless devices for applications that demand proven performance, scalability, and reliability.

The M1030-2 uses a 900 MHz radio to achieve more than 200-meter communication distance outdoors, while consuming

down to 30 μA in a typical network deployment. The combination of extremely high reliability and low power consumption

enables applications that require very low installation cost and low-maintenance, long-term deployments.

The standard serial and discrete input/output interfaces of the M1030-2 give it flexibility to be used in a wide variety of

different applications, from industrial process control to security, to lighting. When integrated into a product, the M1030-2 acts

like a network interface card (NIC)—it takes a data packet and makes sure that it successfully traverses the network. By

isolating the wireless mesh networking protocols from the user, the M1030-2 simplifies the development process and reduces

development risk.

CONFIDENTIAL Pinout 5.0 Pinout The M1030-2 has two 11-pin Samtec MTMM-111-04-S-S-175-3 (or equivalent) connectors on the bottom side for handling all of the I/O. The third pin in each of the connectors is not populated, and serves as a key for alignment. The connectors are mounted on opposite edges of the long axis of the M1030-2. The M1030-2 serial interface (serial protocol is specified in 7.4.1) provides flow control in the receive direction only.

CONFIDENTIAL 6.0 Mote Boot Up 6.1 Power-on Sequence Mote Boot Up The M1030-2 mote has internal power on reset circuits that ensure that the mote will properly boot. However, for the power on reset circuitry to function properly the external power supply must meet the timing shown in Figure 4 and specified in Table 10.
PAGE 10
CONFIDENTIAL Interfaces Figure 7 Vcc Inrush Current 6.3 Serial Interface Boot Up Upon mote power up, the CTS line is high (inactive). The mote serial interface boots within boot_delay (see Table 13) of the mote powering up, at which time the mote transmits an HDLC Mote Information packet, as described in section 7.4.3.7. Once the mote has established wireless network connection, it uses the CTS pin to signify availability to accept serial packets for wireless transmission.

CONFIDENTIAL Interfaces The TSMP 1.0 compliant wireless interface allows a remote monitoring/control application to configure the parameters (such as sample rate, report rate, and thresholds), receive sensor data and to actuate the digital output. For details on integration with remote applications, please refer to a Dust SmartMesh-XT Manager datasheet. Figure 8 Discrete I/O 7.

Upon reception of the packet, the mote forwards it to the network. The format of the serial packet payload is transparent to the mote.
PAGE 15
CONFIDENTIAL 7.4.3.4 Interfaces Command 0x84 Time/State Packet Time data packets use the command type 0x84. The time packet includes the network time and the current real time relative to the Manager. The mote sends this response when it receives a Get Parameter request with time as the parameter (described later).
PAGE 16
CONFIDENTIAL Interfaces 7.4.3.6 Commands 0x89 and 0x8A Get Parameter Request/Response The Get Parameter command allows a number of configuration parameters in the mote to be read by serial. When a Get Parameter Request command is sent, the response to the request is sent within the diag_ack_timeout (see Table 13). The command structure for individual parameter types can be found in section 7.4.4. The length of payload (n) depends on the parameter type and is specified in that section.
PAGE 17
CONFIDENTIAL 7.4.3.8 Interfaces Command 0x8D Reset Mote Upon receiving this command, the mote notifies its children about an upcoming reset, then proceeds to reset itself. The delay to the actual reset depends on the network configuration. Table 25 Command 0x8D Reset Mote Msg Byte Description 1 Data Type Cmd type 7.4.4 Value unsigned char 0x8D Mote Get/Set Command Parameters This section specifies the parameters that may be used with the Set and Get Commands.

CONFIDENTIAL Interfaces 7.4.4.2 Parameter Type 0x01 Network ID The network ID is the identification number used to distinguish different wireless networks. In order to join a specific network, the mote must have the same network ID as the network Manager. This parameter is only valid for the Set Parameter command. Upon receiving this request, the mote stores the new network ID in its persistent storage area, but continues to use the existing network ID.

(All values are in hexadecimal.) Step 1 Define HDLC packet payload: Command type => 87 Parameter => 01 Network ID => 00 7D Note that the additional control bytes do not count against the 80-byte payload limit.
